Just bought a used 2015 ls460 awd recently and the average gas mileage on it is around 19L/100km (roughly 12 MPG) with a mix of city and highway driving. I feel like that's a bit high and there might be something wrong that's driving up the fuel consumption that much. I would say my driving style is fairly economical and I don't really leave the car idling much.
I'm curious what mileage others get and if what I have is normal. TIA

 

I have a 2016 RWD and I average 17 - 18 MPG combined, I manually calculate MPG every time I fill up.

 

I have a 2013 f sport awd and get around 15mpg combined but calculated manually like the above post because there are too many ways to skew results either way using the nav. I don't believe the people here that say they get 30 doing 80 mph, must be doing some special math to get that high above epa ratings, my corolla gets that kind of mileage.

 

I also average about 17 to 18 mpg, mostly city driving in my 2016 AWD using premium.

 

Around town the ‘14 LS460 gets 16-18 mpg. Rarely see 20 or more. The LS430 gets 19-20 routinely and on trips can get 23-24.

 

22.3 average, 32.1 if I'm semi actively trying on an 800 mile round trip. RWD and optimized though so I'm on the high end, I think these get crazy good mpg

 

My 2017 LS 460 tells me "17 mpg" on the dash day after day and I have no reason not to believe it. But I have to admit, some of my driving is done solely to exercise the car, by a run at highway speeds with light traffic.

 

Sounds about right for the city driving. Depending on your driving habits and the environment you can get even less than that, or much better. I'm averaging 12-13 MPG in the city and around 25 MPG on the highway. This is not a Prius for sure. LOL

 

I average 18 on mine, SWB, RWD; combination city/hwy. If I fill up and drive only highway, I can hit 22 or so IIRC. I've only done 1 trip that used the whole tank; that's when I bought the car and brought it home on a 500 mile trip. I can't remember if I beat 22; if I did, it wasn't by much. This was driving through FL, so no hills/mountains. I use top tier premium gas.

 

My 2010 AWD gets around 17 in town, and around 25 on the highway.

 

On my 2014, I get about 18mpg, IF I drove like grandmother (not trying to claim anything about grandmother's), and drove with cruise control at 65mph, never slowing down or speeding up, I could get around 30-32mpg (I tested this going on a 16 hour trip, locked around 65-70, and reset, after the 8 hour stretch of driving, it was showing 32mpg).

 

I believe that to be true, with the 8 speed transmission. I've never been able to drive this car that slow (65MPH), as you're aware it likes to run on highways at a speed well over 75.

 

Yeah. 75-80 is a sweet spot, just around 2000 RPM. I'm curious if that "ECO" mode makes any reasonable difference for the MPG on the highway. Never got a chance to test it on the long trip myself. Have no patience. LOL.

 

LULUMAC, if you’re over 100k miles, spark plugs are due, are both air filters clean, is MAF sensor ever cleaned, tires worn and air pressure? Do you use premium fuel from a top tier gas company. Any extra weight in trunk, how many passengers? All thes things can affect fuel economy.

 

That is very poor mileage. My 2015 LS460 AWD, purchased in January this year, now has 90,000 Klms, does significantly better than that, all hand calculated.
